Innovate Stg1 Supercharger with W/M injection

If I do go with WMI, I was planning to run around with the base tune and let the AEM map out the flow. But I'm curious about the source of your issues now..

I'm just playing it safe and ordered the fuel pump and even injectors. I know I will be running E85 and upgrading the pulley, so I figured what the hell, might as well do it now. (little different since I will run E85 I know)

I think for as cheap as the fuel pump is, might as well just upgrade it. But luckily its something that can always be bought in the future without having to retune or pull something else off that you previously installed.

I would not buy injectors, especially for the stage one kit. The fuel pump is certainly a good idea for the fuel you intend to run. Some injector "upgrades" are far worse then stock, and tuned properly you should easily be able to basically max out the supercharger on the stock injectors.

WMI will "rich" the mixture so a pump isn't necessary.

Thanks for the heads up. Unfortunately I already bought injectors, lol. Keep in mind though I will be running E85.

Maybe I will leave them alone for the time being.

Yes, just do the pump and then do a re tune.

I'm going to try and hold off on a pump until the fuel starvation issue is fixed. I don't want to dig into my tank twice.

Thats a very valid and good idea.

Damn, well there goes my "great" idea of trying to kill two birds with one stone

Hit up the dynojet again to see what the meth tune would do. Got some unexpected results. It is clear the meth tune is probably not the meth tune at all and got mixed up (duplicated) with my 91 oct tune. It made the same exact power as the 91 map.

Several 220-230 whp pulls on the base tune and the "meth tune". I am in contact with the tuner to see what is up. Have lots of logs to send him.

Dyno charts when I get home!

You had pulls with 230whp without meth on 91? nice. I so want to drive one of these, I've never driven a car with a PD blower.

I wonder if that nameless header will do for your kit what the fa20club header is doing for the vortech kit. Jason said he was optimizing the header for the innovate kit, and they don't make bad pipes over there.

Definitely need to figure out what's going on with that meth map..

Are you still running all stock or did you add any bolt-ons?

Also I assume the A/F isn't accurate in the plot? Hopefully you get the W/M figured out, always kinks when you're on the leading edge

Stockeroo! 225 aint so bad on stock stuff =)

I know... At least I found a dynojet shop that takes care of me. $30 for 2 hrs on their dynojet!

Did your meth guy (sounds so bad) discuss any evaporation that can occur by injecting pre-supercharger as the air compresses?

I was talking to the owner of a BMW race shop at a local cars & coffee (they use to race in the Rolex Grand-Am series) and do a ton of WMI (aquamist) on customer cars. He suggested that I'd lose some of the mixture due to evaporation in the compression cycle. Just wondering if you know anything about it. Still considering if I should pursue the WMI or just wait and do the simple intercooler addition (if it's simple).

If he's that experienced with WMI I can assume he knows what he's talking about. But I thought the whole point of WMI is to get it to evaporate. When a liquid changes into a gas (evaporation) it grabs a lot of heat from the surroundings, this is "Evaporative Cooling". It's also why alcohol feels cool when you wet your hand with it.

I figured this was the bulk of what WMI does, and the resulting wet, alcohol-laden, mixture helped with the octane as well. So I'm confused when he says you lose some of the mixture to evaporation.
